MOV to MP4 converter
Convert an iPhone or QuickTime MOV into an MP4 that uploads and plays anywhere. Usually a rewrap, so it finishes almost immediately.

Converted on your device · nothing is uploaded · no size limit
- No upload — files stay on your device
- No signup and no watermark
- No file size limit
Video recorded on an iPhone or iPad is saved as MOV. That is fine until you try to hand it to somebody on Windows or Android, attach it to a form, or upload it somewhere that only names MP4 in its list of accepted formats.
MOV and MP4 are close relatives — MP4 was standardised from the QuickTime format — so the conversion is normally a straight rewrap with no re-encoding at all. If the source turns out to hold something MP4 cannot, such as HEVC in an unusual configuration, the tool re-encodes automatically.
How to convert MOV to MP4
- Choose your file. Drag a MOV file onto the strip above, or click it to browse. The first file also loads the converter itself, which takes a few seconds.
- Wait for the bar to fill. Encoding runs on your own processor. A one-minute 1080p clip usually takes under a minute; keep the tab open while it works.
- Download the MP4. The finished file appears as a download button and saves straight to your device.
Why convert MOV to MP4
Windows and Android stop complaining
MP4 plays natively on both. MOV needs a capable third-party player, which the person you are sending it to may not have installed.
Upload forms accept it
Job applications, learning platforms, insurance claims and client portals commonly list MP4 and nothing else.
It streams properly on the web
The conversion moves the file index to the front, so a browser can start playing before the whole file has downloaded.
No waiting when it can be copied
A rewrap runs at disk speed. A large file that would take twenty minutes to re-encode is often done in well under a minute.
MOV and MP4 compared
| WebM | MP4 | |
|---|---|---|
| Created by | Apple | MPEG standards body |
| Typical source | iPhone, iPad, screen recordings | Cameras, exports, downloads |
| Plays on Windows | Needs a capable player | Natively |
| Plays on Android | Inconsistent | Natively |
| Accepted by upload forms | Sometimes | Almost always |
Doing it yourself with ffmpeg
If you convert files regularly, or need to process a whole folder, run it locally instead. This is the same operation the tool above performs:
ffmpeg -i input.mov -c:v copy -c:a copy -movflags +faststart output.mp4Every flag is explained in the guide to the ffmpeg command.
Questions
Does the quality change?
In the usual case, no. Both streams are copied without re-encoding, so the output holds the exact same video and audio data as the source. A re-encode only happens when the source contains something MP4 cannot carry.
What about HEVC video from a newer iPhone?
HEVC in an MP4 container is valid, so it is usually copied straight across. Be aware that HEVC itself has patchier playback support than H.264 — if the recipient still cannot open it, the ffmpeg command below with libx264 will produce a maximally compatible file.
Will the file get smaller?
Not meaningfully. A rewrap keeps the same video data, so the size stays roughly the same. To reduce size, use the video compressor instead.
Is rotation preserved?
Yes. Orientation metadata written by the phone is carried into the MP4, so portrait video stays portrait.
How big a file will it take?
Up to around 2 GB in a desktop browser. Phone browsers have far less memory available and will struggle well before that.
Is the video uploaded?
No. It is processed inside this page and never sent to a server.
